描述 Description

The ZL30634 is a feature-rich network synchronization solution with up to seven independent DPLLs and five extremely low output jitter synthesizers. This solution is ideal for Synchronous Ethernet (SyncE) central timing applications such as 5G Distributed Units (DU), Centralized Units (CU) and Radio Units (CU).

Other devices in this family include?ZL30731, ZL30732, ZL30733, ZL30734, ZL30735,?ZL30631, ZL30632, ZL30633,?ZL30635, ZL30641, ZL30642, ZL30643, ZL30644, ZL30645 and ZL30640 which are targeted for 5G SyncE and IEEE1588/PTP timing applications.?
